Figures 5 and 6 respectively. Accurate measurements of the ball filling can only be made after the mill is ground out. In this case the mill is operated with the feed turned off until all of the ore has exited the mill. Measurements of the ball level within the mill can then be made. Figure 7 shows an example of the balls in a mill after a ...

10 effective factors for circulating load When increasing pumping energy and pump and cyclone maintenance costs are balanced against decreasing grinding energy and media costs, all as circulating load increases, the optimum economic circulating load can be identified, as it was at Kidd Creek (Table ). [4] The circulating load ratio was lowered from an average of approximately 450% to ...
